INSTALLATION FOR FRACTIONATING FRIABLE MATERIALS LIKE SEEDS OF CEREAL AND OTHER AGRICULTURAL CROPS Russian patent published in 1996 - IPC

FIELD: sorting of agricultural products. SUBSTANCE: grain is delivered from rocking inclined tray 36 into container 1 with quietly flowing water 4. Grains whose specific weight is greater than unity will sink to the bottom. Because of different volume and shape of grains, the water flow will carry them to different distances from the loading tray. Bottom of installation has receiving devices 14 and 15 arranged throughout its length and equipped with hydraulic elevators 12 which carry the separated fractions for drying in sublimating chambers and further, for storage. Grains whose density is lower than that of water are entrained into discharge flow 32 in the upper part of the container. EFFECT: improved design. 5 dwg
